1932 \`configure' configures emacs 24.2.50 to adapt to many kinds of systems.
1933
1934 Usage: $0 [OPTION]... [VAR=VALUE]...
1935
1936 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1937 VAR=VALUE.  See below for descriptions of some of the useful variables.
1938
1939 Defaults for the options are specified in brackets.
1940
1941 Configuration:
1942   -h, --help              display this help and exit
1943       --help=short        display options specific to this package
1944       --help=recursive    display the short help of all the included packages
1945   -V, --version           display version information and exit
1946   -q, --quiet, --silent   do not print \`checking...' messages
1947       --cache-file=FILE   cache test results in FILE [disabled]
1948   -C, --config-cache      alias for \`--cache-file=config.cache'
1949   -n, --no-create         do not create output files
1950       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1951
1952 Installation directories:
1953   --prefix=PREFIX         install architecture-independent files in PREFIX
1954                           [$ac_default_prefix]
1955   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1956                           [PREFIX]
1957
1958 By default, \`make install' will install all the files in
1959 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1960 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1961 for instance \`--prefix=\$HOME'.
1962
1963 For better control, use the options below.

2020                           enable expensive run-time checks. With LIST, enable
2021                           only specific categories of checks. Categories are:
2022                           all,yes,no. Flags are: stringbytes, stringoverrun,
2023                           stringfreelist, xmallocoverrun, conslist, glyphs
2024   --enable-check-lisp-object-type

2026                           type. This is useful for development for catching
2027                           certain types of bugs.
2028   --enable-profiling      build emacs with profiling support. This might not

2031                           Requires GNU Make and Gcc. Enabled if GNU Make and

2035   --disable-largefile     omit support for large files
2036   --enable-gcc-warnings   turn on lots of GCC warnings. This is intended for
2037                           developers, and may generate false alarms when used
2038                           with older or non-GNU development tools.
2039   --enable-link-time-optimization
2040                           build emacs with link-time optimization. This is
2041                           supported only for GCC since 4.5.0.

9695    Here is a matrix of mmap possibilities:
9696         mmap private not fixed
9697         mmap private fixed at somewhere currently unmapped
9698         mmap private fixed at somewhere already mapped
9699         mmap shared not fixed
9700         mmap shared fixed at somewhere currently unmapped
9701         mmap shared fixed at somewhere already mapped
9702    For private mappings, we should verify that changes cannot be read()
9703    back from the file, nor mmap's back from the file at a different
9704    address.  (There have been systems where private was not correctly
9705    implemented like the infamous i386 svr4.0, and systems where the
9706    VM page cache was not coherent with the file system buffer cache
9707    like early versions of FreeBSD and possibly contemporary NetBSD.)
9708    For shared mappings, we should conversely verify that changes get
9709    propagated back to all the places they're supposed to be.
9710
9711    Grep wants private fixed already mapped.
9712    The main things grep needs to know about mmap are:
9713    * does it exist and is it safe to write into the mmap'd area
9714    * how to use it (BSD variants)  */
